Electronic device

Abstract

An electronic device comprises a housing, a pillar and a fixing unit. The housing comprises a side-wall, an opening and a first positioning portion, wherein the opening is formed on the side-wall, and the first positioning portion is disposed in the housing corresponding to the side-wall. The fixing unit comprises an arm, and a second positioning portion, wherein the pillar is disposed on the arm, the second positioning portion is disposed on an end of the arm, the pillar is inserted into the opening to prevent the fixing unit from moving in a first direction and a second direction, the first direction perpendicular to the second direction, and when the fixing unit is in a fixing orientation, the second positioning portion contacts the first positioning portion, the first positioning portion prevents the fixing unit from moving in a third direction perpendicular to the first and second directions.

1. An electronic device, comprising:
 a housing, comprising a side-wall, an opening, and a first positioning portion, wherein the opening is formed on the side-wall, and the first positioning portion is disposed in the housing corresponding to the side-wall; 
 a pillar; and 
 a fixing unit, comprising an arm and a second positioning portion, wherein the pillar is disposed on the arm, the second positioning portion is disposed on an end of the arm, the pillar is inserted into the opening to prevent the fixing unit from moving in a first direction and a second direction, the first direction perpendicular to the second direction, and when the fixing unit is in a fixing orientation, the second positioning portion contacts the first positioning portion, the first positioning portion prevents the fixing unit from moving in a third direction, and the third direction perpendicular to the first and second directions, wherein the housing further comprises a protrusion disposed on the side-wall, and the fixing unit further comprises a third positioning portion, and when the fixing unit is in the fixing orientation, the third positioning portion wedges the protrusion. 
 
     
     
       2. The electronic device as claimed in  claim 1 , wherein when the fixing unit is in the fixing orientation, the second positioning portion wedges the first positioning portion. 
     
     
       3. The electronic device as claimed in  claim 2 , wherein the first positioning portion comprises a notch, the second positioning portion comprises a protuberance, and when the fixing unit is in the fixing orientation, the protuberance wedges the notch. 
     
     
       4. The electronic device as claimed in  claim 1 , wherein the pillar is a lamp, comprising a light source disposed therein. 
     
     
       5. The electronic device as claimed in  claim 1 , wherein the pillar is a button. 
     
     
       6. The electronic device as claimed in  claim 5 , wherein the pillar is integrally formed on the arm. 
     
     
       7. The electronic device as claimed in  claim 5 , further comprising a switch, disposed in the housing corresponding to the pillar, wherein when a user pushes the pillar, the pillar actives the switch. 
     
     
       8. The electronic device as claimed in  claim 1 , wherein the third positioning portion is L-shaped and disposed on another end of the arm.
